ICE-SCRAPER.

To all whom it may concern: l

Be it known that l. FRANK Evans, of 1 Minneapolis, Ilennepin county,Minnesota, have invented certain new and useful Improvements inIce-Scrapers, of which the folj owing is a specification.

My invention relates to machines for cleaning or scraping the surface ofan ice field I preparatory to cutting the same, and the object of theinvention, is to provide a machine by means of which the snow can beeasily and quickly gathered up and delivered to a sled box moving along)eside of or with the machine.

A further object is to provide a machine having a large capacity and onethat will be economical to operate and maintain.

The invention consists generally of various constructions andcombinations, all as hereinafter described and particularly pointed outin the claims.

In the accompanying drawings forming part of this specification, Figure1, is a plan view of an ice scraper machine embodying tical sectionalview of the same, Fig. 3, is a transverse sectional view on the linea;a: of Fig. 2, Fig. 4, is a side elevation, partially in sectionlooking toward the discharge end of the side delivery conveyer.

In the drawing, 2 represents a suitable platform having forward and rearaxles 3 and 4 provided with carrying wheels 5 and 6. The forward wheelshave flanges 7 on their to revent the machine from sli ping or ski dingon the ice. The rear wfieels are loose on the axle having the usualratchet connection 9 therewith and said axle is provided with a beveledgear 10 meshing with a pinion 11 on a shaft 12 which has a knuckle ointconnection 13 with a shaft 14 from which an apron 15 provided with aseries of cross slats 16 is driven. This apron o crates in a box 17 anda frame 18 is hinge at its lower end on the shaft 14 and is providedwith a shaft 19 around which the conveyer belt passes. The frame 18 iscapable of swinging on its pivot and is raised and lowered by means ofcables 20 and drums 21, mounted on a shaft 22 and having an operatingwheel 23. Rollers 24 are preferably mounted on the under side oftheframe 18 len thwise thereof in position to engage the of the sled boxinto which the snow is l Specification of Letters Patent.

discharged, and prevent damage to the slats of the conveyer. A frame 25is hinged on the rear axle and projects forwardly therefrom over thehorizontal portion of the conveyer and a scraper blade 26 is mounted onsaid frame and provided with a cutting edge adapted to rest on the iceand scrape u the snow and deliver it upon the horizonta ortion of theconveyer. Said scraper bla' e is held down to the work by means of rods26 arranged to slide in crank arms 27 on a shaft 28. are put undertension by the depression of the arms 27. An 0 erating lever 30 ismounted on said shaft y means of which the attendant can force the frame25 downwardly and hold the scraper blade in contact with the ice with ayielding pressure. Burs 31 are provided on the rods 26' to be engaged bythe crank arms 27 when said arms are raised for the purpose of liftingthe said frame and raising the scraper blade out of contact with the me.

In the operation of the machine, the scra er blade having been lowered,the snow will e cleaned off the ice' and delivered to the horizontalportion of the conveyer by which it is elevated and discharged intoa boxor other receptacle that is moved along beneath the inclined portion ofthe conveyer.

I claim as my invention:

1. The combination with a wheeled frame,

, of a side delivery conveyer mounted therein and comprisingatransversely operating horizontal portion, said conveyer having adriving connection with the machine axle, a snow scraper blade arrangedin front of the horizontal ortion of said conveyer and means for 1101ing said scraper downwardly with a yielding pressure, substantially asdescribed.

2. The combination with a wheeled frame, of a side deliveryconveyermounted therein and comprising a horizontal and an upwardlySprings 29 are provided on said rods and' inclined portion, means foroperating said conveyer a frame, a snow scraper blade mounted on saidframe in advance of said horizontal side delivery portion, and adaptedto gather up the snow and deliver it upon said side delivery portion andmeans for raising or lowering said scraper blade and said frame.

3. The combination with a frame, having carrying wheels, of a sidedelivery conveyer comprising a horizontal and an upwardly inclinedportion, a frame projecting forwardly above the horizontal portion ofsaid conbe put under tension by the depression of lo veyer, ascraperblade mounted on said frame said crank arms, substantially as described.and projecting in front of said conveyer, a In witness whereof, I havehereunto set shaft mounted on said machine frame and my hand this 17thday of July 1908.

' having an o crating lever, crank arms se FRANK EVANS cured on saishaft, rods pivotally connected with said scraper blade frame and havingWitnesses:

sliding connections with said crank arms and J. A. BYINQTON, springsarranged on said rods and adapted to RICHARD PAUL.
